Ground Source heat pumps allow
homeowners to heat their homes
via utilizing the unlimited heat
stored in the ground...
An air source heat pump (ASHP)
is a system that uses outside air
as its heat source.
Our systems are maintenance free,
however we would recommend a check
every 5 years. We are happy to service
systems not installed by ourselves.
Underfloor supplies a pleasant
comfortable heat that is distributed
evenly around the room...
Alternative Heating & Cooling Ltd was founded by Mike Cotter and Brendan Harte and first registered in June 2001. Based in West Cork , we offer a nationwide service, with various sub-dealers located throughout the 32 counties.
The objectives of the company were originally to feed a small local demand for geothermal, with the company undertaking the complete project, total plumbing, /HVAC package.
Quickly it was realised that the demand was such that the company could not continue to its full potential and it was decided to specialise in geothermal and underfloor solely.
Since then, we have remained focused on supplying quality heat pumps and underfloor heating systems to the domestic and commercial markets.
We are main Irish dealers for Waterfurnace and Euronom heat pumps, and are also suppliers of Panasonic, Nordic and Weider heat pumps.
The heat pump works on the same characteristics as a standard domestic fridge but in reverse, instead of cooling, it heats. Heating and cooling are achieved by moving a refrigerant through various indoor and outdoor coils and components. A compressor, condenser, expansion valve and evaporator are used to change the state of refrigerant from a liquid to hot gas and from a gas to cold liquid.
Heat pump efficiency (COP) is obtained by comparing how much energy it consumes in order to complete the heating and cooling cycle. Coefficient of performance (COP) defined as: “The ratio of heat delivered by the heat pump and the electricity supplied to the compressor”
(COP = Kilowatts Delivered) eg. 7.5kw (Output) ÷ 1.5kw (Electrical Input) = 5 COP
Electricity is needed to drive the heat pump, but for every unit of electricity used, it will generate 3 to 5 units of useful heat. The efficiency of a heat pump will depend mainly on the temperature of its energy source and the temperature at which the heat generated is needed. Basically, the higher the temperature of the heat source is and the lower the temperature of the useful heat is, the more efficient the heat pump will be. A Ground Source heat pump using the soil as a heat source (constant temp of 8°C to 12°C) and floor or wall heating (water temp of 35°C to 55°C) is one of the best combinations, with an efficiency in excess of 450%, compared to an oil or gas boiler with an efficiency of 70 – 85%.
